Digital Trends’ TV Buying Tips:

Should I worry about viewing angle?

Absolutely. All LCDs will distort when viewed from extreme angles, but the degree of distortion and the angle it starts to occur at varies from TV to TV. If you plan to pack a dozen people in front of a single TV for entertaining, viewing angle will make a huge difference for the unlucky few who get scattered off to the sides. Most manufacturers will state viewing angle in degrees (for instance, 160) in the specifications for a TV, but be warned: methods for measuring this very subjective figure vary, and we can guarantee most companies opt for the most generous figures. When possible, try to evaluate it yourself in person, or read hands-on reviews that can offer anecdotal evidence, rather than relying on easily-manipulated numbers.

Do I need an ATSC tuner?

If you plan on watching, free, over-the-air programming, then yes. As of 2009, all over-the-air broadcasts use the ATSC standard. Pretty much all HDTVs manufactured over the past few years will include this feature.

What are widgets?

Many of the top television manufacturers – including Sony, Sharp, Panasonic and Samsung – include Ethernet jacks on the back of their premium televisions for high-speed Internet connectivity (or in some cases, have integrated Wi-Fi for wireless connections). TV viewers will then use the remote to select “widgets,” graphicalicons on the screen that plays relevant (and customized) content ranging from YouTube videos and Flickr photo galleries to local weather, news, sports updates and stock quotes, usually delivered by Really Simple Syndication (RSS). Even more exciting is the partnership between Netflix and various TV companies, such as LG and Sony, allowingtelevision viewers to access tens of thousands of movies on-demand, many of which are in high-definition.

LCD or Plasma?

Debating between LCD or plasma can almost get as subjective as debating between chocolate and vanilla. But unlike the never-ending ice cream debate, there actually is a superior TV choice, depending on how you plan to use it.

Check out some of our previous guides on the subject to get a better look, but in short, plasmas use more electricity, come in bigger sizes, have deeper blacks, don’t suffer from motion blur, and offer an unlimited viewing angle that’s best for off-axis viewing. LCDs are more energy-efficient, have fewer problems with glare due to their matte screens, can hold an image for hours or days without suffering “burn-in,” and generally look brighter.

After deciding which format to go with, our LCD and Plasma HDTV buying guides can help you with more questions specific to your type of TV.

Do I need a 120Hz set? What about 240Hz?

This popular LCD TV-based technology helps reduce motion blur. Pronounced “120 hertz,” 120Hz technology essentially doubles the speed at which frames are displayed, from 60 frames per second to 120 frames per second, resulting in a clearer moving image, especially in fast-action video sequences.

Since the screen can display more frames than a movie actually has, many TVs will artificially generate in-between frames where they don’t exist to make motion look smoother. Some people find the look more fluid, while some people think it looks artificial and odd. Fortunately, all TVs that offer it also offer an option to turn it off, if you don’t like it. We recommend testing it in person to see the effects for yourself before deciding whether or not you should pay extra.
